MC141555

USB Hub Controller

CMOS

This device is a self-contained USB Hub which complies with USB Hub

Specification Rev 1.0. This device is used to expand the USB ports of your PC

system while needed. Because of its self-contained and bus-powered/self-

powered capability, it can hide the complexity from the user and be flexibly

placed anywhere, such as monitor, keyboard, motherboard, Hub-box, etc. The

MC141555 consists of Serial Interface Engine (SIE), Hub Repeater, and Hub

Controller, supporting one upstream port and up to five downstream ports.

ORDERING INFORMATION

MC141555P1 Plastic Dip

Both Low Speed Mode (1.5Mbps) and Full Speed Mode (12Mbps) are sup-

ported by automatically detecting which data line (D+ or D-) is pulled high

whenever downstream devices are connected to the bus or at power-up.

MC141555 Hub can be Self Powered or Bus Powered. When self-powered,

MC141555 is powered by an external 5 volt supply and capable of deliver

500mA current to each downstream port. Power management for all down-

stream ports supports power-switching and overcurrent detection with Individ-

ual or Ganged control; a self-powered MC141555 supports Individual control

only, but bus-powered MC141555 supports either Individual or Ganged control.

When Ganged control, PWRSW1 and OVR1 are dedicated for power manage-

ment.
